FU -LINE v vALvn Application filed May 11, ieze. Serial at. 362,350; I I I This invention relates to new and useful improvements in carburetors.

An object of the invention comprehends the provision of an air valve operable in conjunction with a butterfly valve of the carburetor; t I

Another object of the invention consists of a bypass port in the carburetor to admit air to the cylinders of the engine when same is'coasting in gear with the butterfly valve closed and the ignition cut 05, to provide an air brake and to carry off the usual gaseous fumes from the motor.

With the above and other objects in View, the invention further consists of the following novel features and details of construction to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a fragmentary side elevation of a motor vehicle engine and carburetor illustrating the application of the invention therewith.

Figure 2 is a top plan view of the invention.

Figure 3 is a-longitudinal sectional view taken on line 83 of Figure 2.

Figure l is a detail sectionalview taken on line 4:4: of Figure 3.

Figure 5 is a horizontal sectional View taken on line 5-5 of Figure 3.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character I indicates a relatively. thick gasket interposed 17 at its opposite end secured upon the inner face of the vehicle instrument panel 18. A

control rod 19, passing through the bore of the sleeve member 16, passes through the bore in thegasketlOi of the tubular extension into thegport 20 zontally disposed enlarged'portions' 22 :upon' diametrically opposite sides thereof and pro viding apocket or bore 23 therebetween.

That portion of thecontrol rod-19, extended through the bore 23 in the butterfly valve 21, is shaped-inconformity withsaid bore and heldagainstindependent sliding movement between the portions 22".thr0ugh the instru-' mentality ofa setscrew 2 1. I.

The'remaining depending extremity of the throttle rod l9 is ,projected'outwardly and beyond the gasket 10 and; which I carries in'g elements26 therefor," the purpose of which will be presently apparentg rA bees" or stop-collar, such as 'indicated'at' 27,- carried upon the aforementioned proj ecting portion of the control rod 19; is engageable atone end thereof withthe uppermost end convolution of the compression spring as best shown in Figure 3 of the drawings.

A set screw 28 carried by the boss 27 termi-v natesto provide a stud 29 receivable within a longitudinally disposed slot 30 in the adjaa butterfly valve 21 is provided with horicent portionof the controlrod 19 to provide a wear or thrust adjustment and purchase for the aforementioned end ofthe compression spring. Y r i i I A diskBl, carriedby and right angularly disposed upon the innermost end of the boss 27, has ports 32 adapted for selective regis' tration with passageways 33 in the'body of the gaslret10; the latter being oined for communication with a bypass or port 3 1 located immediately behind the butterfly valve 21 when the latter is shifted tooccupy a closed position, as substantiatedzfrointhe illustration of our invention in Figure 4 of the draw 1 ings.

Under ordinary running conditions, the

ports 32 in the disk 31. willbe disposed out of line and registration with the passageways 33 whereby the fuel mixture drawn up through the intake manifold into the combus tion chambers of the engines will not be quali fied by the mixing of excess air therewith. l/Vhen coasting down hills in gear with the me I 65 thereon acompression spring 25 and adjusts control rod shifted to closed position, to dis-' pose the butterfly valve horizontally and across the bore 20 of the gasket 10, with the ignition shut off, the ports 30 will be aligned with the passageways 33 in the body ofthe gasket 10 to admit air therethrough subse- V quently passing through the bypass or port 34 through the intake manifold 11 andinto the combustion chambers of the engine, upon the suction strokes ofthe pistons therefor; V The compression strokes of each'of the pist tons in the bores of the cylinders will compress the admitted column of air and force same through the exhaust manifold and mufiier whereby gaseous fumes willbe discharged and the motor' cooled off during journey down hill. Each ofsaidcylinfders, upon the compression strokes of each of the pistons therefor, will create separate and distinctlsnubbing actions and which will, in effect, provide a brake for the vehicle whereby the latters service brakes and emergency brake may be saved. r

If desired, a lock, such as indicated at '35, may be employed for the purpose of locking the butterfly valve 21 in close(l,-positio n, upon the instrument panel 18 whereby, unauthorized use of the particularly equipped vehicle will be prevented. T f 4 The invention 1 is susceptible of various changes in its form, proportions'andminor details of construction, and the right ishereinreserved to make such changes as properly fall within thescope of the appended claim. Having thus described the invention, what is claimed is An attachment for use upon carburetors of internal combustion engines comprising a gasket of relatively thickformatioma butterfly valve mounted within the bore of the gasket, said gasket having a multiplicity of passageways in communication with a common bypass port leading into the bore of the gasket adjacent the discharge end of the butterfly valve, a disk included upon the gasket having ports selectively aligned with the passageways, and a control rod common to both the butterfly valve and washer to facilitate synchronization in the closing'of the butterfly valve and the admission of air through the passageways and bypass port into the combustion chambers of the engine. t

In testimony whereof we affix our signatures.
